KITTITAS COUNTY <br />DEPARTMENT OF PUBLIC WORKS <br />PUBLIC WORKS — BOARD OF COUNTY COMMISSIONERS <br />STUDY SESSION STAFF REPORT <br />STUDY SESSION DATE: July 8, 2019 <br />TOPIC: Tipton Road Speed Study Results <br />ACTION REQUESTED: Schedule a Public Hearing Considering a <br />Requested Speed Posting of Tipton Road from <br />Look Road to Hungry Junction Road <br />LEAD STAFF: <br />Mark R. Cook <br />RECOMMENDATION: <br />Schedule a public hearing considering placing speed limit sign on Tipton Road from <br />Look Road to Hungry Junction Road. <br />BRIEFING SUMMARY: <br />• Tipton Road is unsigned for speed currently <br />• Study was conducted in early May 2019 (05/07 to 05/14) <br />• MP 0.0 to MP 0.7 is paved. MP 0.7 to MP 2.0 is gravel <br />• 85`h percentile speed recorded as being 43.70 MPH, maximum recorded speed <br />was 58 MPH <br />• No accidents in the past five years <br />• Approach density is 11 per mile (8 in 0.7 miles) <br />BACKGROUND: <br />Tipton resident Jay Herbers requested the speed study citing people driving very fast on <br />the road. The maximum recorded speed was 58 mile per hour. The 85`h percentile speed <br />was recorded as being 43.7 MPH. Combined average daily traffic volume was collected <br />as being 105, or approximately four cars per hour. <br />DISCUSSION: <br />The speed data suggests average motorist are driving the road at less than the legal speed <br />(unposted 50 MPH). The maximum recorded speed of 58 MPH is not significantly <br />greater than the legal speed limit. Posting the speed limit at 50 MPH may result in <br />elevated speeds from the current 85`h percentile. <br />Kittitas County Code addresses unsigned speed on County Roads at 10.08.030 Fifty <br />miles per hour. <br />Page 1 of 3 <br />PUBLIC WORKS BOARD OF COUNTY COMMISSIONERS WORK SESSION STAFF REPORT <br />
